Hello,

I am having the exact same issue on an intel Q6600 , under fedora 28 , 

kernel : 4.16.5-300.fc28.x86_64

In a fresh Fedora 28 install, ( which has runlevel 5 as default ) suspend
blanks the screen and disables any input, forcing to a hard restart using the
power button. 
Reproductible : always

I am using nouveau : 

Name         : xorg-x11-drv-nouveau
Epoch        : 1
Version      : 1.0.15
Release      : 4.fc28
Arch         : x86_64
Size         : 229 k
Source       : xorg-x11-drv-nouveau-1.0.15-4.fc28.src.rpm
Repo         : @System
From repo    : anaconda
Summary      : Xorg X11 nouveau video driver for NVIDIA graphics chipsets
URL          : http://www.x.org
License      : MIT
Description  : X.Org X11 nouveau video driver.

Setting runlevel defaults to 3 and launching x with startx fixes the issue,
which is perfectly acceptable for me as a workaround. Thank you very much @todd
for the hint.

I'd be glad to provide additional info if it can help.

I have the same problem on an Acer E13 (ES1-311-C4Q6), suspend was working as
ex
pected on 4.14.18 and hangs on all newer kernels I have tried. Was running
Fedor
a 27, just upgraded to 28 and no change.

Working driver:

# modinfo -F filename `lshw -c video | awk '/configuration: driver/{print $2}'
| cut -d= -f2`

@Chen,

I'm going to be tied up for a few weeks, due to a larger than normal workload.
So I won't have time to mess with this bug right now.
In the mean time I will try blacklisting all vid drivers and see what happens.
Although I suspect it will act the same as when the X display manager is
disabled by setting multi-user.target.
But I know it won't be any time this week. Maybe mid next week if I'm lucky.


For the time being though, there are 3 work-arounds listed here that fix the
problem.

1) Change runlevel from 5 to 3 (permanent fix - see opening post + comment #6).

2) Restart your X display manager once you log in. For instance Xfce spins use
Lightdm.  (Temporary fix that lasts until the system is rebooted).
 * See comemnt #16

3) Install another video driver and blacklist Nouveau (permanent fix but a big
hassle if you run secure boot).
 * see comment #5 for manual Nvidia driver install or see comment #7 for
external repository to install Nvidia driver.

I personally don't know anything about the repo listed in comment #7. Whereas
in comment #5, you are downloading directly from Nvidia themselves.

I wish they let us edit our posts here. 

I realized I made a mistake in number 3 of comment #22.

It should say "your systems default video driver" instead of Nouvaeu. Also if
you're using a GPU other than Nvidia than you will obviously need to find a
Intel, or AMD driver you can attempt to install.

Sorry for the confusion. 


@paul. 
Thanks for info.

If this is highly connected with video driver, then bugzilla freedesktop might
be a better place to track this bug down since I've seldom seen any graphic
driver people  jumped into kernel bugzilla to track issues, and they prefer
using freedesktop(at least for i915) AFAIK.

--- Comment #27 from todd (toddsmb@gmail.com) ---
@Chen

After seeing a few responses from people I'm starting to see that this is
definitely not a video driver specific issue. Not everybody is using Nouveau. I
suspected it wasn't from the start because the default generic video driver for
Nvidia (Nouveau) has not changed from the start of fedora 27 to the end of
fedora 27, and the problem didn't start until an update somewhere in the
middle.

So Nouveau was never updated, yet the problem started with a newer kernel. But
that could be a coincidence. So I just checked the update history on this
machine and found that on 2018-02-17 there was a kernel update to 4.15.3 and
there was also another important update that day which could very well be the
problem.

xorg-x11-server-Xorg
and 
xorg-x11-server-common

I had been out of town for a while and thus missed all updates from 4.14.16 to
4.15.3 So any packages between then I don't have a listing for.

With that in mind I remember that the problem does not exist if you restart X
or if you boot into text mode and then manually startX. Plus because Paul just
stated that he is using KDE than I guess that pretty much eliminates the
desktop environment because I use Xfce.

So I think you're right. We need to report this over at freedesktop bugzilla as
well. 

Great, more work :(
I already started a post at bugzilla fedora, they said its likely kernel
related so my post was closed with a note to post at bugzilla kernel. Now I
gotta start a 3rd one. 
If I had lots of time I wouldn't mind. Perhaps we can con you into starting one
over there. If you do, please post link to it. Otherwise When I get more time I
will.

I will change the runlevel to text and see if it resolves the problem. I assume
I can test by typing: "echo mem > /sys/power/state" ?

I just did the runlevel test and it does not make difference for me. I did:

ln -sf  /usr/lib/systemd/system/multi-user.target
/etc/systemd/system/default.target

and a reboot to 4.16.6-302 and ran:

echo mem > /sys/power/state

The power light stayed on and it does not wake up. I tried the same after
booting to 4.14.18-300 that worked fine.

@Paul

Use the correct method to set your run levels.

The original post tells you how and comment #6 even tells you where to get the
information.

read the file....   /etc/inittab   

The correct way is .....

  systemctl set-default multi-user.target  (for text mode / runlevel 3)

  systemctl set-defaulta graphical.target (for graphical mode / runlevel 5)

Read the file /etc/inittab please.

p.s. Almost forgot to mention.  Again, please use the systemctl method. So to
test your systems suspend use.

systemctl suspend

Did you delete all your symlinks?

Also, it sounds like you might just have done a "dnf system-upgrade reboot"
rather than a clean install.?.? Fedora's system-upgrade is a total and complete
P.o.S., most often causing more problems then it's worth. 

I have an idea of some things I need to test but I don't have time ATM to
perform them. I'll post my results when I can get away from work long enough to
run them. Could be a couple weeks.

In the mean time, all I can say that might possibly help you is that I really
think you need to at least try a clean install. Make sure to zero your drive
first. 
Perhaps you already know, but after a file is deleted it remains on the drive
until at some point the physical space the file was using becomes overwritten
by a new file. Plus when simply formatting a drive, it does not delete the old
files on the drive. Even after you install a new OS the old files can still be
recovered, so long as the physical drive space the original file was residing
on is not overwritten.


If you care to run one of the tests I plan to run but don't have time right now
then feel free.


**BE SURE TO IMAGE YOUR DRIVE FIRST IN CASE THIS HOSES YOUR INSTALLED OS's.***
Or don't try it at all if you don't back up all your shit first and expect this
to work perfectly for you. This is an experiment!!


Use....

dnf --showduplicates list xorg-x11-server-Xorg

and 

dnf --showduplicates list xorg-x11-server-common

Use those to enable you to downgrade the X11 server packages to one that was
being used when this problem did not occur.
Specifically version 1.19.5-1.fc27.


**BE SURE TO IMAGE YOUR DRIVE FIRST IN CASE THIS HOSES YOUR INSTALLED OS's.***
Or don't try it at all if you don't back up all your shit first and expect this
to work perfectly for you. This is an experiment!!

Either way, good luck.

As you can see, that version listed above is for fedora 27, not 28 so you will
need to re-install fedora 27 first.

Thanks Samuel, updating to kernel-4.16.14-300.fc28.x86_64 and moving back to
Nouveau rather than the workaround with the NVIDIA driver, suspend and resume
now works again for me too.
